Feats

ITEM CREATION FEATS
Spellcasters can use their personal power to create lasting magic items. Doing so, however, is draining. A spellcaster must put a little of himself or herself into every magic itom of a certain type. Regardless of the type of times they involve, the various item creation feats all have certain features in common.
XP cost: Power and energy that the spellcaster would normally keep is expended when making a magic item. The XP cost equals 1/25th of the cost of the item in gold pieces. A character cannot send so much XP on an item that he or she loses a level. However, upon gaining enough XP to attain a new level, he or she can immediately expend XP on creating an item rather than keeping the XP to advance a level.

METAMAGIC FEATS
Wizards and Divine Spellcasters: Wizards and Divine spellcasters (clerics, druids, paladins, rangers) must prepare their spells in advance. During preparation, the character chooses which spells to prepare with metamagic feats (and ths which take up spell slots higher)
Sorcerers and Bards: Chose spells as they cast them. They can choose when they cast their spells whether to apply their metamagic feat to improve them. As with other spell casters, the improved spell uses up a higher level spell slot. They must apply the feat on the spot. This takes up an extra round.
Spontaneous Casting and Metamagic Feats: A cleric spontaneously casting a cure or inflict spell can cast a metamagic version of it instead. For instance, an 11th level cleric can swap out a prepared 6th level spell to cast an empowered cure critical wounds spell. Casting a 1-action metamagic spell spontaneously is a full round action, and a spell with a longer casting time takes an extra full round action to cast.
Effects of Metamagic Feats on a Spell: In all ways, a metamagic spell operates its original spell level, even though it is preprared and cast as a higher level spell. Saving throw modifications are not changed unless stated otherwise in the feta description. The modifications made on these feats only apply to spells cast directly by the feat user. A spell caster can't use a metamagic feat to alter a spell being cast from a wand, scroll, or other device.
Metamagic feats that eliminate components of a spell dont eliminate the attack of opportunity provoked by casting a spell while threatened. However, casting a spell modified by Quicken Spell does not provoke and attack of opportunity.
Metamagic feats cannot be used with all spells. See the specific feat descriptions for the spells that a particular feat can't modify.
Multiple Items and Metamagic Feats: A spellcaster can apply multiple metamagic feats to a single spell. Changes to its level are cumulative. A silent, stilled version of charm person would be prepared and cast as a 3rd level spell. A character doesn't need the metamagic feat to activate an item storing a metamagic version of the spell.
Counterspelling Metamagic Spells: Whether or not a spell has been enhanced by a metamagic feat does not affect its vulnerability to counterspell another spell.

FEAT DESCRIPTIONS

Feat Name: Description of what the feat does or represents in plain language.
Prerequisites: A minimum ability score, another feat or feats, a minimum base attack bonus, a min number of ranks in one or more skills, or a class level that a char must have in order to acquire the feat. This entry is absent if a feat has no prerequisite. A feat may have more than one prerequisite.
Benefit: What the feat enables the character to do. If a character has the same feat more than once, its benefits do not stack unless otherwise indicated. In general, having a feat twice is the same as having it once.
Normal: What a character who does not have this feat is limited or restricted from doing. If not having the feat causes no particular drawback, this entry is absent.
Special: Additional facts about the feat that may be helpful when you decide whether to acquire the feat.
